Size Guide
Hey Girl! We've got the perfect fit for your finger 💍
Our unique design allows for 3 sizes in one due to our split in the side of the device, which also accommodates to overnight finger swelling.
If you are on the cusp of a size, please size up.
| Kyri | AUS/UK | US |
|---|---|---|
| 1 | H 1/2 - J 1/2 | 4 - 5 |
| 2 | L - M | 5 1/2 - 6 1/2 |
| 3 | O - Q | 7 - 8 |
| 4 | Q 3/4 - S 3/4 | 8 1/2 - 9 1/2 |
| 5 | T 1/2 - V 1/2 | 10 - 11 |
Still not sure about your size? No worries!
If you don’t have a ring that you can use for finding your size, we recommend heading over to a jeweller and having them quickly size your index finger!
P.S - You can totally wear your Kyri on your index, middle, or ring finger! What's important is that you're consistent with the finger you choose and don't alternate between fingers.

What is body literacy?
Body literacy is the foundation of self-awareness.
It’s about truly understanding your body—how it functions, what influences it, and how each phase of your cycle plays a role in your daily life. When you lack body literacy, you’re disconnected from vital signs your body gives you every month—like when you ovulate or how your lifestyle affects PMS and period symptoms. But when you do have body literacy, you’re in tune with your cycle, can predict shifts in energy and mood, and make empowered decisions about your nutrition, stress, fitness, and more. It’s not just about tracking your period—it’s about using your body’s natural rhythms as a powerful tool for living better.

What is basal body temperature?
Think you ovulate on day 14? Think again.
Basal body temperature (BBT) is one of the most reliable ways to confirm ovulation — and it rarely lines up with the "textbook" cycle. Learn how a small rise in temperature can tell you big things about your fertility. -
